COLLAR OR FLANGE FOR STEAM OR HOT-AIR PIPES.

'SPECIFIGATlON forming part of Letters Patent No. 416,294, dated December 3, 1889.

: Application filed June 29, 1889. Serial-No. 315,982. (No model.)

To all whom it may concern.-

Be it known that I, AUGUSTUS M. HOOVER, a citizen of the United States, residing at of Pennsylvania, have invented a new and Pipes, &c., of which the following is a specification.

This invent-ion has relation to collars or flanges for steam, hot-air, and other pipes, and is especially adapted for use in connection with pipes passing upwardly through ceilings, though, as will be hereinafter apparout, certain novel features of the invention may be employed in relation with pipes not inserted through the ceiling, but through the walls, as is well known.

Amongthe objects in view are to provide an ornamental collar or flange that is formed in opposite sections or halves, whereby the same maybe applied to pipes after the latter have been placed in position, and thus avoiding the liability of injury to the collar or flange in working around the same.

A further object of the invention is to provide such sections or halves with means for interlocking to form the completed collar.

A still further object of the invention is to provide the collar with certain adjuncts whereby the collar is adapted to receive securing devices that may be passed from the ceiling through the opening through which the pipe is passed and to the floor above, at which point such devices are adapted to be secured, and thus the careful fitting of the collar upon the pipe not depended upon for the purpose of maintaining the collar in position, but the usual expansion and contrac' tion of the pipe embraced thereby and as caused by the heat and cold may take place and yet the relative location of the collar upon the pipe be undisturbed.

With these general objects in viewthe invention consists in certain'features of construction, hereinafter specified, and particu larly pointed out in the claims.

Referring to the drawings, Figure 1 is a sec-- tional view of a ceiling and floor through which is passed an ordinary pipe, and upon said pipe is mounted a collar or ornamental flange constructed in accordance with my invention. Fig. 2 is a detail in perspective of one of the'sections; Fig. 3, a View similar to Fig. 1,illustrating the pertinenoy of one of the novel features of myinvention to the collars now in use.

Like numerals of reference indicate like parts in all the figures of the drawings.

1 represents the floor, and 2 the ceiling, and through the same are formed opposite openings 3, through which is passed an ordinary pipe 4. p

6 represents the collar or flange, and the same consists of two opposite sections 7 each of which is a counterpart of the other, and a description therefore of one will suffice for both.

In practicing my invention each of the sections 7 is formed from a blank of a substantial U shape, and a sufficient portion of the terminals of the U are bent inwardly toform opposite flaps 8 and 9 and to make the finished section semici rcular in plan, so that when two sections are placed together a complete circular collar is provided. The flap 8 is slotted, as at 10, to provide atongue 11,which extends laterally from the flap. The opposite flap 9 is provided with a transverse slot or opening 12, so that when the two sections are brought together the tongue 11 of one section may be passed through the slot 12 of the opposite sect-ion, after which said tongues are bent to prevent accidental disengagement. In this manner the collar is mounted in position upon the pipe after said pipe has been placed in position, and after all work upon the ceiling has been accomplished, in contradistinction to the usual method of mounting the flange upon the pipe at the time the pipe is mounted in position, and afterward finishing the ceiling. By this subsequent mounting of the collar all liability of marring the collar is avoided.

In stamping the sections 7, of course an opening 13 is formed, through which the pipe 4 is passed, and during this latter operation a lip la is left projecting into the opening 13. This lip 14 is also provided with a perforation 15, so that in the completed collar there will be diametrically-opposite lips. ject of these lips is to receive downwardlyextending wires 16, terminating in hooks 17 at their lower ends, which are inserted through The ob- IOO the perforations 15, said wires depending at each side of the pipe 4, and being passed through the opening 3 of the floor above and secured by tacks or nails 18, which are of course hidden by the usual flanged floorplate 19.

In Fig. 3 I have shown the usually employed ceiling-collar, the same being constructed of an integral piece of sheet metal, and usually depending for its support upon its contact with the pipe. In this figure, 20 represents the collar, and 21 the flange usually depending and encircling the pipe. In applying myinvention to such constructions I employ opposite rods of wire, as 16, having their lower terminals .hent, asat 17, to form hooks engaging With the lower edge of the flange 21 at diametrically-opposite points.

Having described my invention, what I claim is- 1. The pipe 4, adapted to pass through the openings in the floor and ceilings and provided with the collar 6, formed of the opposite sections 7, each of which is provided with an upwardly-turned integral lip 14, perforated as at 15, and the wires 16, bent, as at 17, to engage the perforation of the lip and adapted to be connected to the floor, substantially as specified.

2. A pipe-collar formed of opposite independent halves, each of which is provided with a tongue at one side and a tongue-receiving eye at the opposite side, so that the tongue of one section is adapted for insertion in the eye of the opposite section, substantially as specified.

3. A collar for pipes formed of opposite sections, having their ends inwardly bent to form flaps and having one flap slotted, as at 10, to form a tongue 11, and the opposite flap slotted, as at 12, to receive said tongue, substantially as specified.

4. The pipe 4:, adapted to bepassed through an opening in the floor and ceiling, and the collar 6, encircling the pipe and consisting of the opposite semicircular sections 7, having opposite flaps 8 and f), the former slotted, as at 10, to form tongues 11, and the latter slotted as at 12, said sections being also provided with the perforated tongues 14, and the wires 16, for connection with the floor and bent at their lower ends, as, at 17, and connected with the perforated tongues, substantially as specified.

In testimony that I claim theforegoing as my own I have hereto afiixed my signature in presence of two witnesses.

AUGUSTUS M. HoovER.
